The paper deals with experimental investigation and comparative analysis of velocity measurements in ducted axial fan. Experiments were carried out to investigate the nature of velocity variations in a ducted axial fan at different throttle positions as a function of rotor speed employing both Pitot tube and Hot Wire Anemometer. Quantitative analyses of the magnitudes of velocity measured by a pitot tube as well as a hot wire anemometer are examined and various graphs have been plotted. The percentage errors of velocity level have been determined.
